In late April 2014, a 1 (violence) storm swept through the southern United States, destroying more than $ 1 billion in property and killing 35 people. But a group of migratory(迁徙的) birds in eastern Tennessee sensed the oncoming mess and left long before the first clouds arrived. A year 2 (early), the team had tagged golden-winged warblers ( ) with leg trackers 3 (study) their annual migrations to South America. Two days before the storms 4 (strike)five golden-winged warblers slipped away, traveling nearly 700 kilometers south to the Florida coast.

It's the first time that the birds which normally migrate with the seasons 5 (observe) to slip away when a big storm hits.

【题目】Do you feel sad? Happy? Angry? You may think that the way you show these emotions is unique. Well, think again. Even the expression of the most personal feelings can be classified, according to Mind Reading, a DVD exhibiting every possible human emotion1

In the mid 1800s, Darwin divided the emotions into six types—anger, fear, sadness, disgust, surprise and enjoymentMore complex expressions of emotion were probably learned and therefore more specific to each cultureBut now it is believed that many more facial expressions are shared worldwide2The Mind Reading DVD is a systematic visual record of these expressions

The project was designed by a Cambridge professorHis research team first had to define an "emotion"3Using this definition, 412 emotion terms were identified and discussed, from "afraid" to "wanting"

Then each expression is acted out by six different actors"It was really clear when the actors had got it right," says Cathy Collis, who directed the DVD"Although they were given some direction, the actors were not told which facial muscles they should move4

Someone who has tried to set such rules is the American, Professor Paul Ekman, who built database of how the face moves for every emotionThe face can make 43 distinct muscle movementsEkman has also found that it may not be possible for people to reproduce them artificiallyThe most difficult expression to reproduce is the smileIt isn't only about stretching the lips, but tightening the tiny muscles around the eyes5If we learnt to recognize whether someone was using their eye muscle when they smiled, we would be able to distinguish true enjoyment from false.

A.It shows 412 distinct ways we feel

B.These can be combined into more than 10,000 facial shapes

C.These particular muscles are difficult to control, and few people can do it

D.They decided that it was a mental state that could be introduced by "I feel" or "he looks "or "she sounds"

E.He said the expression of these feelings was universal and recognizable by anyone, from any culture

F.It is as if they are programmed into the brains of "normal humans" wherever they are and whatever their races

G.We thought of trying to describe each emotion, but it would have been almost impossible to make clear rules for this

【题目】 English is full of funny expressions that don’t always make sense. What do they mean? How do we use them? And where did they come from? Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don’t understand the culture behind it. Here are some English idioms based on animals.

When children jump around and act silly, for example, their parents may tell them to stop “monkeying around”. To “monkey around” means to do things that are not useful or serious, or to simply waste time.

But spending time playing with their family pets wouldn’t count as “monkeying around”. Many American families have a pet dog, which keeps the children company and makes them happy. Bu for some reason, which American language experts do not know, Americans use “dog” in a phrase that means to feel unwell. If you are “as sick as a dog”, you’re really, really sick and will have to stay home and rest or even go and see a doctor.

Apart from dogs, cats are also beloved in U.S. households. Sometimes you may hear them mentioned in Americans’ conversations, “I told you to keep that secret, but you have just ‘let the cat out of the bag’!” You probably guessed it — that idiom means to reveal a secret or tell facts that were previously unknown.

Dogs and cats don’t always get along, but they appear side by side in a commonly used idiom. When it rains heavily, people might say it’s “raining cats and dogs” outside.

Bad weather often ruins people’s plans for outdoor activities. But on a lovely day, they can go on an outing or have a picnic in the park. If a swarm of tiny bugs decide they love your picnic food and start to hover (盘旋) around you and your friends, then it would be really annoying, wouldn’t it? That experience perfectly explains why people often tell someone who keeps bothering them to “stop bugging me”.

Idioms are very common in both spoken and written English, so learning them is very important. If you need to understand English, or if you want to speak or write natural-sounding English, you have to learn idioms.

1According to Paragraph 1, idioms are_____.

A.phrases and sentences based on animals

B.expressions with rich cultural background

C.funny expressions that always make sense

D.the total sum of the meanings of the words

2“Monkeying around” can be used to describe children_____.

A.jumping around and wasting time

B.doing something useful and serious

C.playing with monkeys with their parents

D.spending time playing with their family pets

3What can be learned from the text?

A.Dogs and cats are friends by nature.

B.Bugs can be used to show your annoyance.

C.Americans believe cats can give away secrets.

D.Americans know the origin of the idiom “as sick as a dog”.

4How does the text mainly develop?

A.By sharing experiences.B.By making comparisons.

C.By providing examples.D.By quoting experts' words.

【题目】 Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID -19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing – the NCP’s symptoms are similar to the common cold or the flu, but it’s potentially more dangerous.

Viruses could be deadly, like HIV and Ebola. 1 How can they cause so much trouble?

Viruses are non-living organisms approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.

Viruses can infect every living thing – from plants and animals down to the smallest bacteria. 2 Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections bring about no noticeable reaction.

Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. 3 For example, HIV, which causes AIDS, attacks the T-cells of the immune system.

But the basic question is, where did viruses first come from? 4 “Tracing the origins of viruses is difficult,” Ed Rybicki, a virologist at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils (化石) and because of the tricks they use to make copies of themselves within the cells they’ve invaded.”

However, there are three main theories to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.

5 The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers.

A.But what are viruses?

B.For the time being, these are only theories.

C.Once inside, they try to find a host cell to infect.

D.The answer may be even less satisfactory than it now appears.

E.Until now, no clear explanation for their origin exists.

F.Experts are concerned about the bad effect that it had on people’s health.

G.For this reason, they always have the potential to be dangerous to human life.
